  The battery 10 is electrically connected to a charging port 101 for connecting a connection terminal of the charger.

  Note that the charging port 101, the hydraulic controller 92, and the restriction switch 84 are fixed to the main frame 21 in the vicinity of the clutch box 54.

  Such a moving lifting apparatus 1 can be used as follows, for example. Hereinafter, the usage method (action) of the moving lifting device 1 will be described.

  [1] First, the operator of the mobile lifting apparatus 1 attaches the handle 3 and the clutch lever 53 to the main body 2 and assembles the mobile lifting apparatus 1 as shown in FIG. At this time, the rotation angle and / or height of both gripping portions 33 are adjusted.

  [2] Next, the operator inserts the power key 336 into the keyhole portion 337 and rotates the power key 336 clockwise by one step. Thereby, the remaining amount of the battery 10 is displayed on the display unit 333, and the drive unit 4 is turned on.

  [3] Further, the operator rotates the power key 336 one more step clockwise (clockwise). Thereby, the raising / lowering unit 8 is also turned ON.

  [4] Thereafter, the operator places the article to be transported on the lifting platform 7.

  [5] Next, the operator operates the changeover switch 335 to select the forward and backward movements of the mobile lifting device 1. The drive unit 4 is configured to stop when the changeover switch 335 is operated while the mobile lifting device 1 is moving.

  At this time, the changeover switch 47 may be operated to select the moving speed of the mobile lifting device 1 (rotational speed of the motor 41).

  [6] Next, the operator holds the operation lever 63 to release the fixing of the operation lever 63 by the brake stopper 338 and rotates the operation grip 45. Thereby, by operating the drive unit 4, the front wheel 20a is rotated, and the movable elevating device 1 is moved forward or backward to a target location.

  This operation is performed while the front wheel 20a is braked by the braking unit 6 by adjusting the degree to which the operation lever 63 is gripped. In addition, this operation may be performed by moving the movable elevating device 1 by the operator himself / herself in a shut-off state in which the driving force from the drive unit 4 is not transmitted to the front wheels 20a by tilting the clutch lever 53. .

  [7] When the moving lifting device 1 is moved to a predetermined location, the operator holds the operation lever 63, brakes the front wheel 20a, and stops the movement of the moving lifting device 1. In this state, the operation lever 63 is fixed by the brake stopper 338. Thereby, it can prevent reliably that the moving raising / lowering apparatus 1 moves unintentionally.
